Hello Joseph,
Thank you for sharing this with our team.
Without your implementation we cannot be sure what exactly happens. This is why I would ask you to elaborate a bit more on your case.
- Can you send us a screenshot of the diagram before the export and also the exported picture?
- Are the missing pictures in a different format than the others?
- Are the missing pictures in the viewport of the diagram?
- How exactly the diagram is exported? Is it using the built-in image export feature (http://docs.telerik.com/devtools/wpf/controls/raddiagram/features/image-export)?
Additionally, you can prepare some runnable code demonstrating the issue and send it over via support ticket or in the WPF forums (http://www.telerik.com/forums/wpf/diagram).
Regards,
Martin Ivanov
